BALING-PRESS'.

SPECIFICATION forming part of Letters Patent No. 664,987, dated 'January 1, 1901.

Applioationriiled November 11, 1899. SeraiNo. 73 6,597. (No model.)

To all whom, it may concern:

Be it known that I, ANDREW WICKED?, a citizen of the United Statesof America, residing at East Chicago, in the county of Lake and State of Indiana, have invented certain new and useful 'Improvements in Baling- Presses, of which the following is a specication.

My invention relates to certain improvements in baling-presses-of the class inwhich hay, straw, or other similar material is compressed into block form.

The object of` the invention is to provide in a baling-press suitable means for condensing the material to be compressed into a convenient size to be readily inserted into the baling-chamber, means for feeding said condensed material into the chamber, and means for supporting blocks such as are used between the bales in the compression thereof, together with suitable operating mechanism for driving these various parts.

To such end the invention consists in certain novel features of arrangement and construction, a description of which will appear in the following specification and the essential features more .definitely pointed out in the claims.

The invention is illustrated inthe drawings by means of seventeen iigures, of which- Figure l is a side elevation of a press embodying my improvements. Fig. 2 is a detail plan view of the condensing-chamber and adjacent parts. Fig. 3 is a similar View with the upper portion of the vertical walls of the condensing-chamber cut away in the plane 3 3 of Fig. 1. Fig. 4 is a detail plan view of a crank-arm used in the operation of the condenser. Fig.. 5 is a detail vertical section in the line 5 5 of Fig. 4. Fig. 6 is a vertical cross-section in line 6 6 of Fig. 2 looking in the direction of the arrow 6. Fig. 7 is a vertical cross-section in line 7 7 of Fig. 1 looking in the direction of the arrow 7. Fig. Sis a central longitudinal section in line 8 8 of Figs. 2 and 7. Fig. 9 is a detail side view of certain mechanism adapted to actuate the feeding devices, the direction of the view be-l ing indicated by the'arrow9 in Fig. 16. Fig. 10 is a detail horizontal section in line 10 10 in Figs. 1 and 9. Fig. 11 is a detail plan view of a block-supporting bar and dog, the parts above the same being cut away in the plane 11 11 of Fig. 1. Fig. 12 is a detail side elevation of said part with certain portions cut away in the plane l2 12'of Figs. 2 and 11. Fig. 13 is 'a perspective view of the blocksupporting bar. section in line 14,14 of Fig. 11. Fig. 15 is a detail side elevation of the mechanism for operating the feeder, showing said mechanism in a different position to that seen in Fig. 1. Fig.` 16 is an endview ofthe parts seen in Fig. 15 looking-in the direction of the arrow 16, the frame being cut away in the plane 16 16; and Fig. 17 is a detail vertical` cross-section in line 17 17 of Fig. 15.

Referring first to Figs. 1, 2, 3, 6, and 8, the main frame of the press will be seen to consist of a rectangular boX A, supported upon wheels ct a. The compression of the material is accomplished within said box by means Fig. 14 is a detail vertical l of a4 plunger b, (see Fig. 8,) operated by a pair of gears B, journaled in the forward end of the box and connected to said plunger by a pitman b', said gears receiving their move-l ment from such gearing as is ordinarily used in presses of this class. An opening ctx is formed in the top of the box, and above this opening is a condensing-chamber consisting of a pair of horizontally-swinging Side boards C C', carried by arms c c c2 c3, (see Figs. 2v and 3,) pivoted to a vertically extendingl board C2. The side boards C C swing over two horizontal boards D D', supported above and upon opposite sides of the main frame of the machine by means of two longitudinallyextending bars d d', (see Fig. 6,) which also carry the vertical'board C2, to which the side boards are pivoted. The front portionof the condensing-chamber is closed by a wall D2, the side portions of which, curved in arcs, are concentric with the pivots of the side boards. The side boards C C are swung toward each other by means of rollers E E','(see Fig. 3,) traveling immediately above slots e e', formed in the boards D D. The rollers E E engage the outer edges of arms c2 cs in their movement from left to right and crowd the-side boards inward. Said rollers are moved forward and backward by two rods e2 es, which are connected to the plunger b by a crossarms e, which are connected by a transversely-extending bar e7, upon which is secured a condenser E2. Between the bar e7 and the rollers E E are interposed blocks e8, which run in the .slots e e and support the rollers above the board. Upon one of the ends of each crank-arm c is journaled a guide-roller e9, also running in the slot, and upon the opposite end of the crank-arm is pivoted one of the rods e2 e2. The forward ends of the slots terminate in laterally-extending portions, the object of which is to permit of a certain amount of independent motion of the rods e2 e2. When the rollers e9 reach the ends of the slots e e', they swing into the lateral extensions thereof, and the opposite ends of the crank'arms e, to which the rods 'e2 e2 are connected, travel forward without advancing the condenser E2 beyond the edge of the opening ctx, while the feeder forces the hay down through the opening into the baling-ehamber of the press. The side boards C C are thrown outward by the condenser E2 striking cam-surfaces c1 c5 on the arms c2 c3 during its movement away from the opening ctx.

The feeder F (see Fig. l) is carried by vertically-swinging arms fj", pivoted to two standards f2. Thearms ff are oscillated by a pair of bars G, connected at their lower ends to reciprocating mechanism hereinafter described. The upper ends of the bars G pass through a cross-bar g, upon which is mounted a pair of brackets g', to which the arms f are connected. Coiled springs g2 are interposed between the brackets g and the upper ends of the bars G, nuts g2 being threaded upon the ends thereof to engage the springs. The lower ends of the bars G are connected to blocks I'I, lying in the paths of cams I I', secured upon the gudgeons of the gears B and adapted to raise and lower said rods. One of these blocks is seen in Figs. 9, l0, l5, lll, and

17 and, as shown, is bifurcated to form two arms 71, 7t, connected at their lower ends by a bolt 712. The gear-wheel B is formed with a gudgeon b2, journaled in a bracket b3, secured to the sides of the box or frame of the press, and in the ends of said gudgeon is secured the cam I by means of a bolt t', said cam rotating with the gear-wheel B and being adapted to engage the block H and raise the same. The cam I is formed with a fiat bearing-surface t", adapted. at certain `intervals to rest against a shoulder 7L:l upon the block H, and with a curved surface t2, preferably concentric with the axis of its rotation. The shoulder 7b3 is slightly concaved, as seen at 7L4 in Fig. 9, against which the curved surface t2 of the cam I bears at certain intervals. A trigger h5 is pivoted upon the block H at 7L6 and carries upon its lower end a roller 7N, lying in the path of the cam I,'formed upon the outer end of the cam I, said roller being engaged by the cam I to draw the feeder down. The other end of the trigger h5 is formed with an ear hs, in which is secured the rod 7t9, passing through an ear 7Lb upon the block H. A nut 7b is threaded to the end of the rod 7L?, and between the nut and the ear 711 is aspring 71, adapted to yieldingly hold the lower end of the trigger against the block, the object of which is to prevent accidental breakage to the parts in case the machine is run backward for any cause.`

Looking at Figs. l and 9, the cam-surface t2 of the cam I will be seen in engagement with the curved surface 7LAll of the block I-I. The direction of rotation is indicated by the arrows in said figures and the plunger 7) is at the end of its forward stroke, the feeder being held in its raised position by the cam. lVhen the plunger is drawn almost to the end of its return stroke, the cam I has been carried around by the rotation of the wheel B and strikes the roller 7t7, drawing the feeder down and forcing the hay into the baliugchamber. The cams I I are so arrangedand timed with respect to each other that the curved surface t2 leaves the block H the instant the cam I strikes the roller 71,7. The cam I draws the block down by its engagement with the roller 7b2 until, when said block is at its lowest position, its surface 71,3 engages the fiat su rfacet' of the cam I and is instantly raised by said cam as the latter is rotated, the corner 71,c of the cam riding along the horzon tal surface of the block until the curved surface h4 thereof is reached, when the feeder will be held in its raised position by said curved surface t2 until the cam leaves the block. By means of this arrangement the feeder is held at rest during a greater portion of the movement of the plunger and is brought downward to force the hay into the balingchamber and returned quickly during the end of the return stroke of the plunger. In ease the gearing of the press should be run backward the cam I will strike the roller 7N and merely swing the trigger 7t5 upon its pivot without raising or lowering the feeder and without danger of breakage.

The separating-blocks are supported upon a swinging bar K, (see Figs. l1, 12, and 13,) pivoted in the frame of the machine and formed with a crank-ar1n 71;, en gagiug a spring 75, resting upon a bracket 7a2 and adapted to yieldingly hold said bar in a horizontal position. The spring 7c' encircles a rod 7c3, which is connected to the crank-arm 7c and extends through an opening in the bracket 71:2. Vhen the swinging bar K is tilted downward by a block, the rod 793 is swung past the dead-cen ter and the arm 7c engages a stop 7a4 and is held there by the tension of the spring 7s until the plunger l) engages the bar K and returns it to its normal position. A pair of standards L are secured to opposite sides of the frame of the machine and the end D2 of the conde using-chamber. They slightly overhang the interior of the press (see Fig. 3) and have pivoted retaining-dogs 7, with rounded concave faces Z, (see Figs. 11 and 12,) adapted to be struck by the blocks, which are in- IOO IIC

'serte'd between saidstandards and said end.

As the block strikes the curved face Z it tilts the retaining-dog upward and may be pushed by, after which the dog falls back in place and prevents the block from slipping back. A lug Z2 is formed upon the dog (see Figs. ll and 14) and engages the plate Z3 to hold the dog in a horizontal position. The blocks are forced into the baling-chamber by means of a depending arm N, pivoted to the arm f and connected to a bell-crank lever O by a link n. Said lever is pivoted to the frame of the machine at o, and when in the position seen in Fig. l the arm N swings downward and to the rear of the block; but when the bell-crank lever O. is raised the link n is thrown forward, thus causing the arm N to swing down between the standards L, engage the block, and

, force the same down into the baling-cham ber.
